V3 100 LPM SECTIONAL SPOOL VALVE

80

Description The V3-100 sectional spool valve is one of the most compact 100 l/min valve available. Designed for pressures up to 250 bar the valve is available with two, three and four position spool control options and a range of spool types. The lever mechanism is a pressure die casting which totally encloses the spool for added protection. A range of optional ancillary valves are also available to be able to match the requirements of the most complicated and demanding circuits. The V3-100 is also available with solenoid control. It uses powerful yet compact 24 watt DC coils to switch the internal oil pilot to engage the main spool. A damping orifice fitted in the pilot line eliminates the harshness usually associated with standard direct acting solenoid valves and gives a positive feel to the control system. Both manual and solenoid sections can be built into a valve assembly and the solenoid sections have the options of lever override.

Application

Designed to be used in applications requiring a rugged, compact control valve with the option of remote control. Typically in the automotive recovery, recycling and agricultural industries where a mix of manual and solenoid control is essential.

Features Excellent metering characteristics. Excellent load holding. Integral load check valve. Open and closed centre option. Adjustable, pilot operated relief

valve. Robust enclosed lever mechanism. Flow control option. 100% production testing. Environmental protection option. 12 and 24V DC. Soft spool action. Interchangeable with manual

sections. Lever override option. Low coil power drain.

The V3E solenoid valve outlet cover contains a small restrictor valve which maintains a pressure for the solenoid oil-pilot valves. The restrictor valve is avail-able with special options for certain low and high flow applications - contact us for details. The solenoid outlet cover must be used when a solenoid section is present in the valve assembly. It is not suitable for use in assemblies with only manual sections.

V3-100 FLOW CONTROL INTERSECTION

A pressure compensated meter-in type flow control which can be included in V3-100 valve manual or solenoid assemblies. The regulated flow is supplied via the pressure gallery to ‘down stream’ sections, while ‘up stream’ are unaffected. The flow can be continuously adjusted using a knob or preset with a screw and lock nut. A relief valve can be fitted to protect the circuit. It has metering and environmental protect options.

Description A meter-in type flow control intersection, which regulates flow to ‘down stream’ sections only. Pressure compensated, it returns the excess flow to the tank gallery. This ensures consistent control and minimum heat generation.

Application To be used in applications requiring precise speed control in addition to stop, start and reverse functions of the spool valve, such as winches, hose reels and industrial conveyors. It can also be used to control the speed of cylinders.

Features Minimum heat generation Pressure compensated Adjustable or pre-set Screw or knob adjusted Relief valve option Limited max flow option Hardened components for

CIRCUIT DIAGRAM

V3 INTERSECTIONS

SERIES CONNECTOR Hy-Pro series connectors are designed to be fitted between two valve sections, connecting in series the actuators that they control. Series connectors are often used to synchronize two hydraulic motors where the return oil from one is fed to the inlet of the second. The series connector effects only the valve sections immediately upstream and downstream of its position in the valve bank. Other sections remain connected in parallel. When using the series connectors, consideration must be given to upstream sections. This is because the normally open tank gallery in the valve bank is pressurized when the series connected actuators are on load. If this is a problem specially designed inlet covers are available which contain a separate outlet port for the relief valve bypass flow.

Special provision has also to be made for ancillary valves when used with series-connected valve banks. In such cases, customers are advised to discuss their circuit design with Hy-Pro.

Description This intersection connects the up stream tank galleries to the pressure galleries of the down stream section enabling the flow to power a second service .

Application Used where two or more services are required to operate simultaneously with differing loads. Often used to synchronize two hydraulic motors.

Features Used with standard

sections. Converts both manual

and solenoid sections. Anodised option

V3-100 ROTARY LEVER

Description The Hy-Pro rotary lever has been developed specifically to enable the operator precise control of motors and cylinders. The lever swings through an 180° arc and works by means of a scroll which converts the rotary action of the lever into axial movement of the spool. The centring mechanism has a friction detent feature which positively holds the spool in neutral then maintains the

Because of the geometry of the lever it is not possible to include it in multi-section valves but it is retro-fitable to existing V3-100 single
